My sagos were damaged during the cold winter here in Pensacola, FL. Lots of the limbs are brown now. How do I prune these plants safely?

It is hard to say how well they will grow back. Sago palms do not deal well with lost fronds, but they have been known to recover fine.
I have several sago palms that were subject to 19 degree weather. What can be done to get them green again?
It is hard to say how well they will survive. Sagos have a hard time regrowing leaves that have died. Once the weather has warmed up in your area, prune away any parts of the fronds that are brown or yellow, as these are dead and will not return. After that, it is really just a waiting game. Give it TLC, and it may make it but it may not.
My two sago palms froze this winter. They are brownish yellow. I don't know if they will come back or if I need to trim off the dead parts, or do I just need to start over?

This year we had a pretty hard freeze. Now my sago has mostly brown and brown/green leaves.
You can cut off the brown fronds, as these are dead. However, do not cut any of the green, as they won't regrow. This article may help you with getting them to recover: https://www.gardeningknowhow.com/plant-problems/environmental/tips-for-saving-cold-damaged-plants.htm
The temperature dropped to 18 degrees for two or three nights. Now the fronds on my palm are brown. Do I need to cut them all off?

My large sago palm's leaves are brown from freezes. The pups are still partly green and the lower leaves on the palm are still a little green. I saw some the other day that the leaves had been trimmed all the way back to the trunk, and I was trying to find out what to do.
I am sorry to hear about your plants. Cut off brown fronds but don't cut any green growth. This article may help you with getting them to recover: https://www.gardeningknowhow.com/plant-problems/environmental/tips-for-saving-cold-damaged-plants.htm
